I'm not getting this error with the SVN code, I'll try to reproduce with the 
1.3 release; can either of you provide gdb output or a pcap that can be used to 
replicate the bug?

I will wait for reaver 1.4 may bee i made the mistake, after the 3rd start of 
walsh it does not exit with this buffer overflow.

Buffer overflows are never a user mistake, always a developer mistake. I will 
try to reproduce the problem on my end; if this happens again, please let me 
know.

I apologize for my bad English. After compilation, I did "make install" so it 
did not create the /etc/reaver/reaver.db. After creating without error, no 
buffer overflow. Output from gdb will supply later.

Thanks for the pcap, I can now reproduce the bug here.

Found the bug in the parse_beacon_tags function; pcap helped a lot, thanks 
much. Fix has been checked in. 

FYI, there appears to be a lot of corrupted data in the captures you are 
getting.
